The whistle is produced by a female voice, adding a unique timbre that further differentiates it from the usual whistles one might hear. The woman's vocal control is evident, as she swiftly modulates between softer and louder tones, creating an urgent yet controlled sound. The whistle is both a call and a command, a vocal signal that immediately grabs your attention.
